Arba'een Pilgrimage
The Arba'een Pilgrimage is the world's largest public gathering that is held every year.[1][2] This Ziyarah[3] is held at the end of the 40-day mourning period following Ashura, the religious ritual for the commemoration of the Prophet Mohammad's grandson Hossein ibn Ali's death in 680.[4][5] Arba'een marks a "pivotal event in history"[6] in which the pilgrims make their journey to Karbala on foot,[7] where Husayn ibn Ali, the third Imam of Shia, and his army were killed and beheaded by the army of Yazid I.[1] Some of the pilgrims make their journey from cities as far as Basra, about 500 km away by road.[8]
